Review of waterpower classifications and withdrawals, Pit River basin, California
Sterling R. Osborne
1974, Open-File Report 74-64
The purpose of this report is to evaluate the existing waterpower classifications of the Geological Survey in the Pit River basin relative to the most recent water resources information and planning. A detailed description of Geological Survey classifications is given on pages 40 and 41. In a following section each...
Search for geothermal seismic noise in the East Mesa area, Imperial Valley, California
Hariharaiyer Mahadeva Iyer
1974, Open-File Report 74-96
The U. S. Geological Survey made seismic noise measurements in the East Mesa area of Imperial Valley, California, to find out if a noise anomaly was associated with the Mesa thermal anomaly. Thirty-three locations were occupied in the area using slow-speed tape-recording seismic systems. One of the stations (CEN) was...
Hydrology of the abandoned coal mines in the Wyoming Valley, Pennsylvania
Jerrald R. Hollowell
1974, Open-File Report 74-237
Mine-water discharge, into the Susquehanna River degrades the river's quality during periods of low flow to a point critical for subsistence of aquatic life. To determine what measures are required to provide a better quality mine-water discharge in the Wyoming Valley, mine hydrology and mine-water quality are related to mine-pool...
Summary of hydrologic conditions and effects of Walt Disney World development in the Reedy Creek Improvement District, 1966-73
Arthur L. Putnam
1974, Open-File Report 74-339
The Reedy Creek Improvement District (hereinafter called the RCID) is an area of about 43 square miles (111. square kilometres) in southwest Orange and northwest Osceola Counties. Before development of Walt Disney World began (mid-1967), all of this tract of land was scrubby flatlands and swamp. Walt Disney World facilities...
Storage of low-level radioactive wastes in the ground; hydrogeologic and hydrochemical factors
Stavros Stefanu Papadopulos, Isaac Judah Winograd
1974, Open-File Report 74-344
The status of mathematical simulation techniques, as they apply to radioactive waste burial sites, is briefly reviewed, and hydrogeologic and hydrochemical data needs are listed in order of increasing difficulty and cost of acquisition. Predictive modeling, monitoring, and management of radionuclides dissolved and transported by ground water can best be...
Hydrology of the Dismal Swamp, Virginia-North Carolina
William Francis Lichtler, Patrick Neil Walker
1974, Open-File Report 74-39
The Dismal Swamp, on the border between eastern Virginia and North Carolina is one of the few remaining large (approximately 210,000 acres) areas of wet wilderness in the eastern United States. There has been much speculation concerning the hydrologic conditions that led to the formation of the swamp.Oaks and Coch...
Geochemical survey of the western coal regions; first annual progress report, July 1974
Jon J. Connor, Ronald R. Tidball, James A. Erdman, Richard J. Ebens, John R. Keith, Barbara M. Anderson
1974, Open-File Report 74-250
National energy needs have precipitated an increased interest in the development of a large coal-based electric power industry in the western United States. This anticipated development has, in turn, spawned a great deal of interest in the environmental impact consequent upon the mining and utilization of these coal supplies. Numerous...
Analog-model studies of ground-water hydrology in the Houston District, Texas
Donald G. Jorgensen
1974, Open-File Report 74-113
The major water-bearing units in the Houston district are the Chicot and the Evangeline aquifers. The Chicot aquifer overlies the Evangeline aquifer, which is underlain by the Burkeville confining layer. Both aquifers consist of unconsolidated and discontinuous layers of sand and clay that dip toward the Gulf of Mexico. Heavy...
Dissolved-solids discharge to the oceans from the conterminous United States
Donald K. Leifeste
1974, Circular 685
Dissolved-solids data from 54 river basins for 1966-69 were used to compute the amount of dissolved material contributed to the oceans from the conterminous United States. The computations show that about 264,000,000 tons are discharged annually. The Gulf of Mexico receives the largest load, about 183,000,000 tons, of which about...
Molybdenite in the Montezuma District of central Colorado
George J. Neuerburg, Theodore Botinelly, John R. Watterson
1974, Circular 704
The Montezuma mining district, in the Colorado mineral belt, is defined by an assemblage of porphyry, ore, and altered rocks that originated in the venting of a Tertiary batholith through weak structures in Precambrian rocks. The ore consists of silver-lead-zinc veins clustered on the propylitic fringe of a geometrically complex...
United States Geological Survey Alaska program, 1974
Claire Carter
1974, Circular 700
This report on the Alaskan activities of the U.S. Geological Survey contains up-to-date accounts of recent results and summaries of plans for the summer of 1974. It is organized in six parts: (1) responsibilities and services of the Geological Survey; (2) organization of the U.S. Geological Survey; (3} Alaskan field...
